Specification of Letters Patent.

To all whom it may concern:

Be it known that we, ARTHUR Gnonon Booznn, Jr., and GEORGE HILL, both citizens of the United States, residing at Tucapau, in the county of Spartanburg and State of South Carolina, have invented certain new and useful Improvements in Dofiing-Machines for Spinning-Frames, of which the following is a speci cation.

This invention relates to certain new and useful improvements in dofiing machines for spinning frames, the purpose being to provide a bobbin carrier or magazine from which the bobbins may be successively delivered to bobbin placing mechanism on the spinning: frame to be placed thereby upon the empty spindles on the. spinning frame, such carrier being mounted upon or carried b I the spinning frame instead of being carmed by the dotting mechanism.

One of the purposes of this invention is to relieve the traveling doffer of the weight of the magazine and bobbins necessary to supply the spindles on one side of the spinning frame, and in carrying our invention into use we prefer to provide the-spinning frame with a structure or support that carries longitudinal magazines which are maintained so that the magazines may be raised above the plane of the creel-board, so as not to interfere with the operatives in laying up roving on the creel-board.

In our prior ap lications we have shown different types of obbin magazines or carriers mounted upon the dofier-frame and operatively connected thereto. Those magazines under certain circumstances do not meet all the requirements of automatic dofiing mechanism, for instance a spinning frame having a hundred and twenty spindles on one side would require one size of magazine, whereas another spinning frame having a larger number would necessarily take a much higher magazine, therefore the dofiers for one spinning. room would have to be sup lied with magazines 'sufiicient to supply bobbins to the longer spinning frame, and where the spinning frames are exceedingly long the magazines will have to be of such a size asto be objectionable as a part ing the doffer frame of the weight of the magazine and bobbins the work laid upon the motor is more constant, and the dofi'er is morereadily handled, especially in moving from one frame to another.

In the accompanying drawings Figure l is an end elevation showing one form of bobbin carrier and a dofier frame constructed for cooperation therewith. Fig. 2 is a front elevation of the dofler frame and magazine, parts of the spinning frame being shown in dotted lines, and Fig. 3 is a ,detail perspective View of a part of the bobbin carrier.

The spinning frame is of the usual type and has attached thereto rails 1 and '2, which provide horizontal ways, the upper rail having on its under side indentations with which the teeth of an intermittently driven spacing wheel engage to move the doffer frame intermittently along the spinning.

frame. The dofier frame is provided with supporting wheels for engagement with the upper. track or way, and with guide wheels that engage the under side of the lower rail, such mechanism and the operative parts of .the' dofi'er mechanism being fully set forth in an application filed March 16th, 1909, Ser. No. 483,821. i

The doifing means may be briefly described as comprising a bobbin-grasping device 3 mounted upon the upper end of a vertically reciprocatory bar 3*, movement being imparted to said bar by a rotary gear or crank 3 and intermediate connecting links and arms indicated by reference numeral 3. The gear 3* receives motion from a vertical shaft 3* which is operatively connected at its lower end to a driving motor 3*.

The spacing wheel 4 which engages'with the rail 1 for advancing the dofi'er along the s inning frame, is fixed upon 'a shaft 4 whic partial rotations from the shaft of gear 3*.

'Also fixed on the shaft 4* is a gear 5 with Patented June 8, 1915.

"of a portable dofling machine. By relievis arranged to receive intermittent tained shaft 10, the latter shaft having on its inner. end a gear 11 that meshes with a gear 12 on a stub-shaft 13, which projects laterally from a bobbin receiver 14;, and by use of the mechanism hereinbefore mentioned an intermittent revolving move ment is imparted -to,the member 14.

The revoluble bobbin receiving member 14 is provided with a longitudinal opening, the ends thereof being enlarged to receive the enlargedbase portions of thebobbins, and the actuating mechanism for this member is so organized that during the intermittent travel of the dofier mechanism a half turn is given to said revoluble member, and after said turn such memberis locked ina vertical.

-- position for the reason that the shaft of the spacing wheel 4-is also looked tohold the dofier frame in positive engagement w th the spinning frame.

Between the revoluble member 14 and the vertical standard of the dofler. frame there is a segmental plate or guide 15 which W1ll revent'a bobbin dropped into said revolu- 1e member from falling out of the same during its :movement .upon its axis. This segmental plate may be attached to the up- .per end of the bobbin tube 16 or to the upper support therefor, and at its upper part the segmental lplate carries a funnel 17 through which a bobbin passes when. 'released from the magazine.

The bobbin releasing mechanism, is intermittently actuated and comprises an oscillatory plate 18, connected at its upper end by a link'19 to the depending member of a bell- -crank' 20, the forwardly extending arm of said bell-crank being connected'to the lower end of a bar 21 which is attached at its upper end to a forwardly projecting arm of a bell-crank 22, mounted near the upper end of the standard, the latter bell-crank being connected to a retractor 23. by a link 24.

' The retractor 23 is maintained in sliding engagement with. a horizontally maintainedarm 25, which projects rearward or toward the spinning frame, sucharm being provided with a follower or Presser-26 shaped to engage a bobbin when in the m azine.

supporting standard 27 is provided with suitable bearings or supports for-the parts hereinbefore described. "It will be noted that the retractor 23 is operatively. connected to the means described in said'application Serial No. 483,821 for holding a bobbin in the gu1de1tube'16, the only: change in the o eratiye parts beingj-to extend the end of e oseillatorymember upward in preferably though not necessarily, in vertical alinement with thezlongitudinal axis of the spindles of the. spinning frames The bobbin magazine or carrier 28 comprises a top-plate 29, an inner depending side 30, the lower end or edge being inturned to provide a bobbin engaging portion, and a frontside plates being carried by resilient bars 34 attached to the front side-pieces 31 and provided with depending ends which lie in the path of the retractor 23. It will be seen that themagazine has at intervals retractile parts which when moved against the action of a spring will release a bobbin, the openings and the retractile members of the magazine being spaced practically the .same distance .apart as the distance between-the spindles.

As the'dofi'er frame stops so' that the guide tube is 111 line with the'spindles, a bobbin will be released from the magazine.

The bobbin magazine or carrier is sup.-

ported at its ends or at intervals by rods 35 which depend from cross-bars 36, said crossity of the magazines is equal to the number 7 of spindles, and in practice the follower 26 will move the bobbins along the magazine.

A magazine of the construction shown can be readily filled from either end, and the bobbins are-held with their large ends upward and depend from the magazine. This 5 style of stationary magazine is attached directly to the spinning frame and may be filled by use of a, detachable hopper constructed to carry sufiicient bobbins to supply the magazine, the latter having a mark thereon to indicate when enough bobbins or quills have been inserted to supply all the spindles on one side of the spinning frame.

It will be seen that the magazine constitutes av track or guide along which bobbins .are' movable longitudinally of the spinning frame into. alinementgwith the respective spindles.

It isobvious'that the particular form of construction of the magazine and its support 1 may be varied so long asthesame-is kept within the terms and scope'of the claims.
